When should I start and with what?

I plan on taking the LSAT in spring/summer of next year. When should I start studying for it, and what should I start with? I don't know what first step to take. I took one practice LSAT awhile back and I scored a 160 on it. The logic games are what tore me up the worst. Any advice you can give will be appreciated!

Well, I'd like a 180, but that's not going to happen. If I can get high 160s or even 170 I think I could be satisfied with that. My GPA is no problem as it's high 3.8s and will be about 3.9 by the time I graduate. I just want to get into the best law school I can.
